Method and system for packet transit through IPV4 networks connecting IPV6 nodes and LANs in a utility grid using tunneling technique
First Claim
1. A wireless communication system comprising:
- a plurality of utility nodes capable of receiving commodity utilization and status information, the utility nodes connected in an IPv6 utility network;
at least one access point connected to the utility network, the access point providing communication to at least one IPv4 wide area network;
at least one node capable of communicating using IPv6, the at least one node in communication with the access point through the IPv4 wide area network; and
wherein an IPv6 tunnel is established from the at least one access point to the at least one node through the IPv4 wide area network.

Abstract
One example embodiment provides a method and system where LAN nodes in an IPv6 utility network are able to communicate with an IPv6 node through and IPv4 network. An access point associated with an IPv6 LAN in the utility network establishes an explicit or configured tunnel to an IPv6 node or and IPv6 network through and IPv4 network. In one preferred embodiment the IPv6 node is a back office system communicating through an IPv4 WAN with the IPv6 node in the utility network LAN using the access point in the LAN. The access point communicates with the back office system through the IPv4 WAN to establish a “6 in 4” tunnel through the IPv4 WAN. A tunnel broker may maintain the “6 in 4” tunnel through the IPv4 WAN between the access point and the back office system.

15. A method of communicating, comprising:
-
receiving the IPv6 packet sent from a utility node at an access point associated with the IPv6 LAN, wherein the sent IPv6 packet is received from a utility node in the IPv6 LAN and intended for an IPv6 node connected to an IPv4 network; and forwarding the received IPv6 packet in an IPv6 tunnel through the IPv4 network to the intended IPv6 node connected to the said IPv4 network. - View Dependent Claims (16, 17, 18, 19, 21, 26, 29)
